Status Bar Displays
The status bar is always displayed with 3 panels of information:
JAWS Alerts:
The alerts panel shows the JAWS turbulence alerts for each alert area.
This panel is identical to JAWS Alpha Alerts display.
|
|
See the Alpha Alerts Display
section for more details about this display, the alerts, and the alert areas.
|
Current Surface Winds:
The current surface winds panel shows wind information from the JAWS anemometers.
Wind direction is the
direction the wind is coming from measured in degrees clockwise
from magnetic north.
Wind speed is measured in knots.
|
|
-
Column 1 contains an abbreviation for each of the anemometers:
EC:
Eaglecrest
MR:
Mount Roberts
SM:
Sheep Mountain
|
CF:
CenterField
PD:
Pederson Hill
08:
Runway 08 (West)
26:
Runway 26 (East)
|
-
Column 2 contains the wind direction (rounded to the nearest ten degrees)
or "CLM" if the wind speed is less than 3 knots.
-
Column 3 contains a '/' and then the average wind speed over the last 1 minute
(rounded to the nearest knot).
-
Column 4 contains a P (for Peak) and the speed (in knots) of the
peak wind speed that occurred in the last 1 minute.
|
If there is no current anemometer information available for a station,
Columns 2-4 display "NA" (Not Available)
Sensor Data Status:
The status display displays the current time and the status of anemometer
and profiler data streams.
|
|
The top line displays the current UTC date
(month/day/year) and time (hours:minutes:seconds).
Column 1 lists abbreviations for the anemometers and wind profilers:
Anemometers

Wind Profilers

EC: Eagle Crest
MR: Mount Roberts
SM: Sheep Mountain
CF: Center Field
| PD: Pederson Hill
08: Runway 08 (West)
26: Runway 26 (East)
| ND: North Douglas
LC: Lemon Creek
SD: South Douglas
|
Column 2 displays the valid time of the most recent data received.
Valid time is
defined to be the time the product was produced by the system, i.e., at
the end of the data averaging interval and
is expressed as hour:minutes:seconds in UTC. If no valid time is displayed
for a sensor, it indicates that the data feed for that sensor is down and
the time of the last valid data is not known.
Column 3 displays the status (OKAY, DOWN or IMPAIRED) of the anemometers
and profilers.
|
Status: Impaired
If the status of a sensor is "impaired",
then the row will be highlighted in YELLOW
and Column 3 will display "IMPAIRED".
A sensor is considered "impaired" if some, but not all, of its data is
not available.
This is likely to be a data quality problem and
NOT a data ingest or data feed problem.
Specifically an anemometer site will show
"impaired" if either its wind speed or wind direction (but not both) is
bad. A profiler site will show "impaired" if all range gates of either
the u or v wind component of the "rapid update" winds
are not available, but there
are some range gates with a valid wind component.
Status: Down
If the status of a sensor
is "down" then the row will be highlighted in RED,
and Column 3 will display "DOWN".
A sensor is considered "down" if none of its data is
available. This could either be a data ingest, data quality,
or data feed problem.
